Product Selection Guide
These FluiDyne V2020 double vane pumps are all Vickers replacement pumps, sharing core mounting, pressure, and port specs, but differ from single stage vane pumps in their front/rear pump flow combinations, port orientation, maximum speed, shaft type, and rotation direction. For alternative displacement options, see the V20201F10S10S11AA30L – FluiDyne V2020. These differences impact suitability for various hydraulic system layouts and flow requirements.
?? Important: The specifications shown are for reference and comparison purposes. Always verify specifications with the official manufacturer documentation or contact our technical team at (800) 823-4937 specifications applications before ordering or review our hydraulic pumps family for additional support to ensure compatibility with your application. We cannot accept returns due to specification mismatches.
| Model Number | Flow Rate | Max Pressure | Displacement | Mounting |
|---|---|---|---|---|
| WF8251035 (Current) | 9 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251091 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251074 | 11 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251014 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
| WF8251052 | 12 | 2500 PSI | 19.5 cm³/r (1.19 in³/r) | 2-Bolt Flange (SAE “A” size) |
Key Differences
Front/Rear Pump Flow (GPM)
Difference: WF8251035 has a 9+8 GPM split; WF8251091 is 11+6 GPM; WF8251074 is 11+7 GPM; WF8251014 and WF8251052 are 12+2 GPM.
Selection Guide: Select based on your required total and split flows—higher front pump GPMs suit applications with primary circuit demand, while higher balance between front/rear is ideal for more even dual-circuit needs.
Total Flow & Speed Limit
Difference: WF8251074 offers the highest total flow (18.0 GPM, 2500 RPM), others provide 14.0–17.0 GPM with varying speed caps (WF8251014/1052 capped at 1800 RPM, others up to 2500–2800 RPM).
Selection Guide: Choose WF8251074 for highest flow or consider V201P5P18C11R – FluiDyne V20 Pump for similar performance; select WF8251035 if you need 17 GPM at up to 2800 RPM. WF8251014/1052 should be used where lower speed is acceptable.
Port Orientation
Difference: WF8251035/1074 have both outlets inline (0°); WF8251091: front outlet 90° CCW, rear 180°; WF8251014: both outlets opposite inlet (180°); WF8251052: inline (0°).
Selection Guide: Choose inline (0°) for simple, straight piping layouts; select 90° or 180° options for tight installations or specific manifold arrangements.
Rotation Direction
Difference: WF8251035/1074/1014 are left-hand (CCW); WF8251091/1052 are right-hand (CW).
Selection Guide: Match pump rotation to your drive motor—critical for correct installation.
Shaft Type
Difference: WF8251074 uses a 13-tooth splined shaft; others use straight keyed shafts.
Selection Guide: Select splined shaft for higher torque or where splined couplings are already in use.
Maximum Speed
Difference: WF8251035 supports up to 2800 RPM; others limited to 1800–2500 RPM.
Selection Guide: Choose WF8251035 if your system requires higher operating speed.
Quick Selection Guide
If you need: Highest total flow and speed (up to 18.0 GPM at 2500 RPM)
Choose: WF8251074
Because: Provides 11+7 GPM split, left-hand rotation, and a splined shaft for robust high-torque applications.
If you need: Balanced dual-circuit output with high speed (17.0 GPM up to 2800 RPM)
Choose: WF8251035
Because: Offers a near-even 9+8 GPM split, left-hand rotation, and inline ports—ideal for systems needing two similar flows. For larger displacement options, see V201P13P3A11R – FluiDyne V20 Pump.
If you need: Majority flow on front section, right-hand rotation
Choose: WF8251091
Because: Delivers 11+6 GPM, right-hand rotation, and a unique port orientation for specialized layouts.
If you need: Max front section flow, minimal rear flow, left-hand rotation
Choose: WF8251014
Because: Best for systems where the primary circuit demands much higher flow than the secondary, with both outlets opposite the inlet for distinct piping runs.
If you need: Max front section flow, minimal rear flow, right-hand rotation
Choose: WF8251052
Because: Similar to WF8251014 but with right-hand rotation and inline ports for different drive and layout requirements.
Compatibility: All models use SAE ‘B’ 4-bolt flange mounting and 1-1/16″-12 UN-2B thread ports, ensuring 100% direct Vickers interchangeability and simplified installation. For systems requiring integrated functionality, explore our pumps with integral valves.
